The secret of lively spirits, even temper, and magnetic presence can never be attained in the world without a perfect circulation of the blood. It may be out of season to say that people often keep themselves too cold; but lay the hint away till next October, when the weather changes, and mark the facts. Our seasons are two thirds cold or chilly; our habits are sedentary, which tends to reduce the force of the system; as a people we are not of excitable temperament; and yet stout men and hearty doctors, who go rushing through their business all day, complain because women sit in overheated rooms, and can not endure draughts in the halls. There is but one answer to this: Nature is her own guide, and it is one of her laws that no creature can be uncomfortable in any way without losing by it. If the tone of the system is so low that a woman feels chilly in a room at seventy degrees, put the heat at once up to eighty, or higher, till she feels luxuriously warm. Chilliness is a symptom to be most dreaded. When the blood forsakes the skin, it clogs the heart, the internal organs, and lays the train for those diseases of the time--neuralgia, paralysis, rheumatism, and congestion. In fact, every person who suffers from one of these stupid chills is in a state of incipient congestion. How hateful is the miserable economy which stints fires in the raw days of May and September, because the calendar of household routine decrees that it is not the season for stoves and grates! Not less irritating is it to sit with a circle half shivering in a large parlor, because the full-blooded, active master of the house has decided that it is nonsense to turn the heat on. The slow tortures such unfeeling people inflict on their innocent victims will be witnesses against them some day, to their great surprise.
